<p>I am considering enabling <code>-Znew-llvm-pass-manager</code> in a big codebase to work around <a href="https://github.com/rust-lang/rust/issues/66617">https://github.com/rust-lang/rust/issues/66617</a> which has been extremely troublesome for us, but I wasn't able to find any kind of tracking issue. What is the current state of this feature and anything I should be aware of? limitations, platform compatibility, etc</p>
